In addition,he used some facts that ancient people may use their unique ways to record summer solstice rather than astronomical cognition. as he states that scientific progress is non inevitable, there is no warranrty that scientific advancement will increase. as long as we have the belief to live better, the scientific advancement is non indispensable nor necessary.
